1 前言

一个问题，一篇文章，一出故事。
今天，笔者的sftp服务器用户登陆异常，使用如下命令查看SSSD服务的状态，

systemctl status sssd.service

可见如下错误提示，

Jul 01 12:35:05 azsftp01 sssd_be[6832]: GSSAPI Error: Unspecified GSS failure.  Minor code may provide more information (Server not found in Kerberos database)
Jul 01 12:35:06 azsftp01 sssd_be[6832]: GSSAPI Error: Unspecified GSS failure.  Minor code may provide more information (Server not found in Kerberos database)
Jul 01 12:35:08 azsftp01 sssd_be[6832]: GSSAPI Error: Unspecified GSS failure.  Minor code may provide more information (Server not found in Kerberos database)

2 最佳实践

2.1 执行退域操作

realm leave cmdschool.org

2.2 重新加域

realm join -U administrator cmdschool.org
